The ability to place a linked file into a document as of Photoshop CC 14.2 made my day. I've been eager for this feature ever since I first started using regular smart objects.

That said, when I open a file in which a link has been changed, the current process for getting the new content looks like this:

1. Remember whether the file might have any linked content.
2. Go find the link. When out of date, the layer containing the link is marked with a warning icon. Finding it may be as simple as checking the layers panel, or it may require the user to sort through some layers.
3. Right-click on the name area of the linked layer. A contextual menu appears.
4. Click "Update modified content" or "Update all modified content".

Would it be possible to match InDesign's behavior, in which a dialog appears on opening the file and offers to automatically update all links? This removes the user's burden of remembering to check for updates and reduces the entire process to one button click.
